ARM: dts: exynos: Mark 1 GHz CPU OPP as suspend OPP on Exynos5250

BugLink: https://bugs.launchpad.net/bugs/1836802
commit 645b23da6f8b47f295fa87051335d41d139717a5 upstream.

1 GHz CPU OPP is the default boot value for the Exynos5250 SOC, so mark it
as suspend OPP. This fixes suspend/resume on Samsung Exynos5250 Snow
Chomebook, which was broken since switching to generic cpufreq-dt driver
in v4.3.
